The standard OILCO o-ring is a single-point pressure seal design. Contained within opposing grooves, the compression along the sealing surfaces promotes a positive adherence while maintaining rotation and keeping friction loss to a minimum.
The OILCO v-ring is a triple seal configuration, spring energized and self-adjusting for normal wear. A Teflon® spring adapter and equally spaced compression springs force the three interlocking seals to flare and constantly maintain an optimal positive seal.
Buna-N is standard, but Viton, Teflon®, Kalrez®, Chemrez®, EPDM and EPR are available options in either format, depending on the product and customer requirements.
